This is one of my personal favorite dinners. And if time is on your side, it's extremely easy.
Beef Tips & Noodles
Cut any size roast into bite-sized pieces. Shake beef cubes in a gallon ziplock bag with enough flour to coat each piece. In a large skillet, brown beef in hot oil with salt and pepper. Add one can of beef broth for a medium roast, more or less depending on the amount of beef. Cover and simmer all day, stirring occasionally. Serve over wide egg noodles.
(*Note: I make this recipe on the stove top but it could probably easily be converted for a slow cooker.)
